automake's make install seems to create directories using mkdir when it should use install to get the permissions right. Thanks to Bruno Haible for the analysis below.

This comes from the MKDIR_P and INSTALL_DATA values that are substituted in lib/Makefile. On my system I see MKDIR_P = /arch/x86-linux/gnu/bin/mkdir -p INSTALL = /arch/x86-linux/gnu/bin/install -c INSTALL_DATA = ${INSTALL} -m 644 INSTALL_PROGRAM = ${INSTALL} INSTALL_SCRIPT = ${INSTALL} which explains why the creation of a subdirectory is sensitive to your umask and the creation of installed files is not. The code which creates the installation directory is found in lib/Makefile.in, generated by Automake: install-nobase_includeHEADERS: $(nobase_include_HEADERS) �...@$(NORMAL_INSTALL) test -z "$(includedir)" || $(MKDIR_P) "$(DESTDIR)$(includedir)" �...@list='$(nobase_include_HEADERS)'; test -n "$(includedir)" || list=; \ $(am__nobase_list) | while read dir files; do \ xfiles=; for file in $$files; do \ if test -f "$$file"; then xfiles="$$xfiles $$file"; \ else xfiles="$$xfiles $(srcdir)/$$file"; fi; done; \ test -z "$$xfiles" || { \ test "x$$dir" = x. || { \ echo "$(MKDIR_P) '$(DESTDIR)$(includedir)/$$dir'"; \ $(MKDIR_P) "$(DESTDIR)$(includedir)/$$dir"; }; \ echo " $(INSTALL_HEADER) $$xfiles '$(DESTDIR)$(includedir)/$$dir'"; \ $(INSTALL_HEADER) $$xfiles "$(DESTDIR)$(includedir)/$$dir" || exit $$?; }; \ done As you can see, it uses $(MKDIR_P). If it were to use instead $(install_sh) -d -m 0755 it would behave as you wish. Please report this to the bug-automake mailing list. Bruno -- http://rrt.sc3d.org
